Evernote security compromised

Saturday, March 2nd, 2013

A security investigation at Evernote, makers of the popular note-taking and document storage map that claims to help users “remember everything,” has concluded that an attempt was recently made to access secure areas of the Evernote service. While Evernote is not affiliated with Missouri State University, we know a lot of our users are fond of the application and want to urge all of you to ensure your accounts are secure. As a precaution, Evernote has reset all of its users’ passwords, so if you use Evernote, you should change your Evernote password soon to continue using that service. If you use the same password anywhere else, you should be sure to change your password on those services as well.

A security best practice is to user unique passwords for each account you hold. Otherwise, when one service is compromised, your password may then be compromised everywhere you use it.

If you need any assistance changing your passwords for Missouri State University accounts, please don’t hesitate to contact the Computer Services Help Desk.

Zero-Day Exploit of Java 7 Prompts Recommendation to Disable Java

Wednesday, August 29th, 2012

Last night we read that a zero-day exploit of Java 7 would allow attackers to load and run software on an infected computer. Computers with Java 7 can be infected just by visiting a website, and there is currently no defense against this attack of than disabling Java. Subsequently, it is recommended that users either downgrade to Java version 6 or disable Java entirely.

Because Sungard Internet Native Banner does not work with Java 7, we have been advising staff and faculty to continue using version 6, but if you have upgraded to 7 we recommend you disable Java using the steps on the Experts Documentation Wiki.

If you have any questions or need assistance, please do not hesitate to contact the Help Desk.

Scam Blizzard.net Email

Monday, February 28th, 2011

Whether or not you play World of Warcraft, you may be receiving emails indicating that your Battle.net account has been compromised and locked down. The emails ask you to visit a site and log in to unlock your account. While these emails and the web site to which they direct you look legitimate, they are not.

Please note that the web site to which you are taken to “restore access to your account” is displayed as us.battle.net in the email, which is the actual Battle.net site, but you are taken to “us.battle.account-service-mangement.net.” While this looks legitimate, the site is actually account-service-management and us.battle are subdomains the phishers have created to steal your account.

Always be wary of entering your password in response to an email request, even if the site looks legitimate. Double check the site address, or go to the site you know is real manually rather than using the hyperlink. As a reminder, you should use different passwords for different accounts to improve your security, and for World of Warcraft I recommend using a Battle.net Authenticator (also available as an iPhone app and an Android app).

The below is an example of the scam email. Please just delete this email, as your account has not been compromised and no action is needed. If you have already responded to this email or logged in via the site it provides, change your Battle.net password immediately and be sure to change your passwords anywhere else you use the same login credentials.

Subject: Too Many Attempts Warning

Dear customer,

Due to suspicious activity, your Battle.net account has been locked. You tried to login your account too many times (403). We are concerned about whether your account has been stolen. In order to guarantee the legitimacy of your account, we need you follow these steps:

Step 1: Secure Your Computer

In the event that your computer has been infected with malicious software such as a keylogger or trojan, simply changing your password may not deter future attacks without first ensuring that your computer is free from these programs. Please visit our Account Security website to learn how to secure your computer from unauthorized access.

Step 2: Secure Your E-mail Account

After you have secured your computer, check your e-mail filters and rules and look for any e-mail forwarding rules that you did not create. For more information on securing your e-mail account, visit our Support page.

Step 3: Restore access to Your account

We now provide a secure link for you to verify whether you have taken the appropriate steps to secure the account, your computer, and your email address. Please follow this site to restore the access to your account: <hyperlink removed>

If you still have questions or concerns after following the steps above, feel free to contact Customer Support at <hyperlink removed>

Sincerely,
The Battle.net Account Team
